Mastering Embedded Linux Programming

By: Chris Simmonds

Overview of this book

Mastering Embedded Linux Programming takes you through the product cycle and gives you an in-depth description of the components and options that are available at each stage. You will begin by learning about toolchains, bootloaders, the Linux kernel, and how to configure a root filesystem to create a basic working device. You will then learn how to use the two most commonly used build systems, Buildroot and Yocto, to speed up and simplify the development process. Building on this solid base, the next section considers how to make best use of raw NAND/NOR flash memory and managed flash eMMC chips, including mechanisms for increasing the lifetime of the devices and to perform reliable in-field updates. Next, you need to consider what techniques are best suited to writing applications for your device. We will then see how functions are split between processes and the usage of POSIX threads, which have a big impact on the responsiveness and performance of the final device The closing sections look at the techniques available to developers for profiling and tracing applications and kernel code using perf and ftrace.

Other tools in the toolchain


The following table shows various other commands in the toolchain together with a brief description:

Command

Description

addr2line

Converts program addresses into filenames and numbers by reading the debug symbol tables in an executable file. It is very useful when decoding addresses printed out in a system crash report.

ar

The archive utility is used to create static libraries.

as

This is the GNU assembler.

c++filt

This is used to demangle C++ and Java symbols.

cpp

This is the C preprocessor, and is used to expand #define, #include, and other similar directives. You seldom need to use this by itself.

elfedit

This is used to update the ELF header of ELF files.

g++

This is the GNU C++ front-end, which assumes source files contain C++ code.

gcc

This is the GNU C front-end, which assumes source files contain C code.

gcov

This is a code coverage tool.

gdb

This is the GNU debugger.

gprof

This is a program profiling tool.

ld

This is the GNU...
